Rear Shock Absorber for 2010-2013 Mazda 3 - KYB 553390

Restore firm, controlled damping to the rear of your car with the KYB Gas-a-just shock absorber, part number 553390. This high-pressure monotube gas shock drops in as a rear replacement for the 2010-2013 Mazda 3, with components and valving designed specifically for the Mazda 3 MazdaSpeed. Available as an OE monotube replacement, it's built to restore your vehicle's original capabilities.

The Gas-a-just runs two separate working chambers: an air-free hydraulic piston and valve area for responsiveness and control, and a second high-pressure nitrogen gas area with a floating piston for a comfortable ride during normal driving and added performance on demand.

• High-pressure monotube design: separates the gas and oil for fade-free operation and instant response.
• Up to 25% more damping: adds damping performance over original equipment shocks, with extra damping for vehicles that work, tow, and run larger, heavier tires and wheels.
• Triple chrome-plated piston rod: an ultra-smooth rod helps reduce seal wear, since fluid leaking can be a cause of shock failure.
• Quick response: higher gas pressure is designed to improve steering response and helps keep Electronic Safety Systems performing as intended.

This KYB gas shock absorber fits the 2010-2013 Mazda 3. To reduce noise and vibration, KYB recommends installing new shock mount components (SM5619) and protecting the rod with a KYB Strut Boot (SB125).
